  1. PS to Loren, I think the site is GREAT! The electric air pump that injects air into the exhaust system operates for approximately 30 seconds when the car is started cold. I am sure you are hearing the electric air pump. Do you think the noise is getting louder?
  2. There was an article written in the Porsche Club magazine Panorama about the failures of the 986 engines. Apparently the manufacturer of the engine cases had some problems and a cylinder would come loose. I have seen a few, and Porsche sells a complete engine for very little money, last time I checked it was $5500.00. Sorry to hear it happend to you.
  3. Are these Technical Booklets still available? Please post the new ones as they become available. These Tech Booklets are the most informative publications Porsche produces. Thanks-Gary
  4. The best way to know if your battery is fully charged is to use a battery hydrometer. You do not want to use the vehicle's alternator to recharge the battery. The alternator was never designed to recharge a dead battery, and the alternator can be damaged attempting to recharge the battery. A Maintenance battery charger will turn itself on when the battery is low, and will turn itself off, when the battery is charged. It is so much easier using a Maintenance Charger, then to attempt to revive a dead battery. It is very risky using jumper cables to start your car, even if everything goes correctly, you may have damaged an electronic component from the surge. The battery's #1 purpose is to start the car, #2 is to act as an electrical shock absorber (capacitor). A weak battery can not absorb the everyday common surges in the electrical system.
  5. It is not unusual for the battery to go dead if the car sits unused for 30 days. Loren's suggestion of using a maintenace charger is excellent. WorldPac has just come out with a new line of "exact fit" batteries that use the AGM design similiar to the Optima batteries (no fluid to leak or vent). The WorldPac batteries are also "reasonably" priced.
  6. Not that specific issue....sorry. But I was drawn to your post because I also have an 01 and recently replaced the bank2 O2 sensor (upstream, before the cat).........now today I'm getting PO175, PO155, and PO172 (in that order of priority). I'm not seeing any of those on the Renntechs OBD list but the generic meaning on those is too rich on bank1, the O2 heater circut bank2 sensor 1, and then system too rich bank2. I'm probably going to reset and fill up at a dif filling station.......see if they pop up again.........other advice welcome & appreciated. <{POST_SNAPBACK}> It has been a while since you posted this, what finally happened?
  7. What type of oil are you using and how often do you change it?
  8. In the future, mark the coil hold down screws with nail poilsh paint. If the paint is not cracked or broken, they did not remove the coils. If they don't tell the truth about one thing, when are they telling the truth?
  9. I am assuming your car is a 996tt? The air pump is electrically operated and will only operate on cold starts, and will only operate for approximately one minute. If the noise goes away completely, after one minute, it could be the electric air pump. If the noise verys with rpm , and does not go away, I would suspect the serpentine belt rollers. Lets us know what you find. Thanks-Gary
  10. I have had this problem on a few 996tt, the noise sounds like a bad power steering pump. Sometimes the noise is so bad you are afraid to drive the car. The problem is the serpentine belt roller. If you remove the belt, start the engine, and the noise goes away, then turn or spin each item, you should be able to feel the bad one. Tell us what you find. Thanks-Gary
  11. Is the fuel NO LEAD, or does it contain LEAD ? If your knock sensors are retarding the ignition spark on your present fuel, then adding higher octane fuel could theoretically improve performance. How about trying it and tell us what you feel? Thanks-Gary
  12. The flashing MIL means that a misfire is happening at that instant, and this misfire can severely damage the catalytic convertors. What proof or evidence is there that the problem is caused by the ignition coils? When you bring the car in for service, make sure you ask them to provide you with ALL the codes stored in the fault memory. They had a chance to fix it right one time, now you need to be involved with the repair. The vehicles capability for measing an engine misfire is so sensitive, you may never feel the misfire. A lean fuel mixture could cause an engine misfire, and there maybe codes relating to the lean fuel mixture. Ask them why they think the ignition coils are at fault, or are they just guessing. Please let us know how it turns out. Thanks-Gary
  13. P0172 Oxygen sensor adaptation (fuel trim), at idle, for Bank 1, below limit. P0175 Oxygen sensor adaptation (fuel trim), at idel, for Bank 2, below limit. I think this could be a code for 1) Mass air flow senosr, 2) fuel pressure, 3) Purge valve. Because the code terminology is so poor, can you look at the OBD2 "Freeze Frame" information, and report the Fuel Trim numbers? It is extremely important to know whether the fuel trim is positive or negitive. You could remove the purge valve and bench test its operation. But if you disconnect it or plug it, you may get more codes. Please let me know what the Freeze Frame Fuel Trim numbers are. Thank you-Gary
  14. I have seen the 7.5 amp fuse blow and cause this same problem. In one case a cell phone charger was installed and connected to this fuse. There should be a chart on the fuse panel cover describing each fuse.
  15. If you check your Owner's Manual, I am sure it will recommend 5W-40, or 5W-50. You should be able to get that oil from Castrol, Mobil, Pentosin. Was that the information you were asking?
  16. Excellent procedure and invaluable data. Thank you - Gary
  17. These 3 pictures show the Purge Valve located on the engine of a 2002 996 tt. The purge valve is part of the fuel vapor system, that is why it is not in your vacuum hose diagram. Why do you want to know about the Purge Valve?
  18. I have never used them,but it sounds like a bargain. How did you find them?
  19. If you ran the engine with the oil filler cap off, or if the cap did not seal, this could cause the MIL (Malfunction Indicator Lamp - offical SAE term) to turn on. You will have to read the code to be sure. If the problem has been corrected, the MIL will eventually turn off. You would think with all the technology these cars have, there could be an LED screen to display the OBD2 codes.
  20. Do you want to open the front trunk because the battery is dead? I have had this problem numerous times, the front trunk will not open when the battery is dead. I connect a full size battery to the cigarette lighter socket, then close all the doors, lock the car with the remote, wait one minute, unlock the car, then pull the front hood latch. Tell us how it works out.
  21. The best way to perform this is with a "coolant exchanger" machine. The machine gets hooked up to the engine coolant hose and you visually watch the new coolant go in and the old coolant come out. Usually you exchnage it past the specified volume, so you get all the old coolant out. I doubt there is any other way to do this, especially with the radiators up front and all the plumbing. You can do a Google on Coolant Exchangers, companies like RTI and SnapOn sell them. Tell us how you make out.
  22. Assuming the engine stopped running because you ran out of fuel, it should have restarted after your numerous attempts. I wonder if your immobilizer is preventing the car from starting? If you turn the key off and then turn it on, you should hear the fuel pump run for a few seconds. If you cycle the fuel pump a few times, that should prime the fuel rail, and the car should start, if the only problem was you ran out of fuel. Lets us know what happens.
  23. Hi Sinbad; Did you have your battery go dead, or did you disconnect your battery? Going in for repair will not get your car to pass the OBD2 Monitors. You need to drive a special "drive cycle" for the CAT and EVAP to pass. I recoomend you try driving your car on the highway at a steady 55 to 60 mph and the RPM at approximately 2500 rpm. Drive like this for over 3 minutes and try not to vary the postion on the accelerator pedal. If you can drive longer then 3 minutes as described, that would be better. Then go to your State Inspection Tester, I think you will find that the OBD2 Monitors passed. Tell us how it went.
